Column editing in Notepad++ is awesome. How can I copy/paste in column mode?

Let's say I have a document like this:

A

A

A

B

B

B

How can I put the Bs after the As on each line, like this:

A B

A B

A B


Solution 1:

It's simple:

  1. Hold the Alt key and select the B lines as columns
  2. Cut or Copy the selection (Ctrl-x or Ctrl-c)
  3. Hold Alt and select the column to the right of the As
  4. Paste (Ctrl-v)
